A Muslim chef employed by the Metropolitan Police is launching a discrimination claim after he was asked to cook pork sausages and bacon.

Hasanali Khoja is accusing the force of religious discrimination after it refused to guarantee in his contract that he would be excused from handling pork products.

The case is the latest in a series of discrimination rows which have engulfed the force, contributing to the resignation of Sir Ian Blair as commissioner last month as well as the suspension in September of Assistant Commissioner Tarique Ghaffur, Britain's most senior Muslim officer, who claims he has suffered racial discrimination.
